On the assessment of multiaxial fatigue damage under variable amplitude loading
In this work, the performance of the SSF criterion is evaluated under variable amplitude loading conditions. The main objective was to inspect the validity of the hypothesis in which the SSF damage map remains valid for any high strength steel. In order to achieve that, fatigue life correlation of...

| description | In this work, the performance of the SSF criterion is evaluated under variable amplitude loading
conditions. The main objective was to inspect the validity of the hypothesis in which the SSF damage map
remains valid for any high strength steel. In order to achieve that, fatigue life correlation of the 1050QT steel
and 304L stainless steel was analyzed under multiaxial loading conditions. The loading block considered in the
study comprises 360 proportional loading cycles with different stress amplitude ratios and stress levels. Despite
being made of proportional branches, this loading block is a non-proportional loading due to its principal
directions variation. This feature allows the evaluation of combined loading effects under variable amplitude
loading conditions, which makes this loading block suitable to mimic the loading effects usually found in the
field. Results show very good agreements, which reinforces the aforementioned hypothesis. |
